| Abstract: | Metal-halide perovskites (MHPs) materials have been prepared into heterojunction nanowires (NWs), which have recently been widely used in micro/nano scale optoelectronic devices. This work designs a core–shell structure Si@perovskite NWs improve the optical response of perovskite material. Si NWs have strong light scattering ability, with a maximum scattering efficiency factor (Qsca) of 15.52 at a radius of 80 nm. The optical response efficiency factor of perovskite NWs is poor, and the maximum values of the Qsca and absorption efficiency factor (Qabs) at a radius of 80 nm are only 2.05 and 2.80. In Si@perovskite NWs, by using Si NWs as the core and perovskite material as the shell, the scattering of Si NWs is utilized to enhance the light absorption of perovskite materials. This result shows that the maximum Qsca and Qabs of perovskite NWs reached 3.86 and 6.25, respectively. In addition, under the AM 1.5G spectral irradiance, the total scattering and absorption of perovskite materials in the Si@perovskite NWs are 3.86 and 1.23 times higher than those of perovskite NWs. This provides a new design for improving the optical response of perovskite NWs. [ABSTRACT FROM AUTHOR] |
